7. Generate and follow the render
The Price card shows the total in credits and, if something is still missing, exactly what (for example a voice not picked yet). Press Generate: the screen walks the steps — waiting in line, faces, direction, opening frames, voices, video (all acts at once), editing, finishing. Cancel stops after the current step.
If some acts are refused by the video generation, the render stops and lists them: change their frame or lines and continue — what was already made is kept, and you pay only for the rest.
